It is looking increasingly likely that a weekend storm system will usher in a period of much colder weather Saturday through part of the following week. A strong cold front will arrive late Friday or early Saturday and will bring modified arctic air from western Canada to our area, along with the chance for some spring snow. This system is still a ways out, so much can change in the forecast, but people with agricultural or gardening interests should continue to watch the forecasts this week.
